Mary, I may still have the schematic on the 747i. Unfortunately, the TV is in East Texas and I'm at work in Louisiana. I'll gladly take a look next time I'm home and see if I can find the schematic and post up a copy if I'm successful.

Hey Rarjar

can you send me the latest firmware for 747-B11 my email is (t.pro68@gmail.com) thanks in advance! and the instruction on how to load new firmware

...However, still interested in purchasing a used, fully working 747i though.

Mine still works like a charm! I'm trying to save up for a 70" set. If you live near Seattle it might be worth taking a look at mine Ah, I see your in the Big Apple ( used to live in the village for a short time) Shipping would be prohibitive.

THUD2?! WOW! Nice to hear your 747i is still kicking along - no hiccups. Yeah, too bad I am in Fort Apache. Too bad you could not visit your old stomping ground and bring the set with you. I have been in touch with dad1153 - he is here (in NYC, not in my apt. ) with me.

Yeah, it's still kickin. I wasn't watching it much after I bought the projector but now (right at the start of football season *%#&*# it!) the projector has bit the dust, so watchin the 747i again. still love it!

WOW! You stuck a fork in the projector? Its done? At least you had a few good years of theater style movie watching. Can it not be fixed? I mean, why go backwards from projector to TV?

If you sell the 747i, what will you watch since the projector is done?

However, still interested in purchasing a used, fully working 747i though. With issues like this, not sure how much longer this set has. Have any of you 747i owners - those of us having problems with the set - taken the back cover off of the set in order to blow dust (using condensed air of course) off of the back of the main board? I'm seriously thinking about doing it. Not sure if it would help prolong the life of the set but at this point, it may not hurt.

Happy 2016 747iers!

My nine (9) year old set has gone back to the intermittent sound problems. Has anybody found a fix for this issue? Otherwise, the set works.

I'm thinking about this for workaround for OTA TV sound:

Although it sits packed up in a box, I still have my 3808CI Denon AVR that works. So, I'm thinking going from optical out from the 747i to optical in on the Denon to get sound from OTA source. Does anyone having the same sound issues as I, have their set hooked up in this configuration? I'm wondering if I bypass the on board speakers, will I be able to receive sound using this config. I won't need the sound to come from the set itself. I had it hooked up this way for a few years prior to December 2013 when I upgraded my AVR and set and it worked with no problems. Only thing, I didn't have the sound dropouts like I'm having now. I'd hate to drag it out and set it up and it doesn't work, albeit, I may have to try it out. Hopefully I have an extra optical cable lying around that I can use for testing. Not like I can make a quick trip to RadioShack that used to be across the street from me to pick one up for testing purposes.

Hopefully somebody sees this Bat signal in the sky and replies in haste.

Just had to replace my 747. The picture started getting bad, contrast was messed up. When you first turn it on, you couldn't see anything on the screen. As it warmed up it got slightly better, but not much. I just purchased a cheap Samsung 55" to replace it. I think the Olevia picture was better

I take it the Samsung is 4K, or you would have said "The Olevia picture was DEFINITELY better"

My friends still have their 747 and constantly tell me that the picture is still terrific. I went to visit (diff state) recently and was pleasantly surprised at the picture when connected to a good source!

Hi everyone, I'm looking for an Olevia twin tuner main board for the 747i part number sco-p508201GS10-NS1. My set has die and I would like to repair it. If anyone knows where to get one please let me know. Thanks!
